This is a species that may be of interest for North American mushroomers. It resembles a large form of H. olivaceoalbus. Here’s what I found in a canadian paper:

“Hygrophorus korhonenii Harmaja, Karstenia 25: 42. 1985.
A circumboreal Picea associate. Known from Fennoscandia and Québec, always with Picea (Harmaja 1985. Hansen and Knudsen 1992). Harmaja (1985) states that H. olivaceoalbus (Fr.) Fr. sensu Hesler and Smith does not fit the European concept of H. olivaceoalbus, but does fit the description of H. korhonenii.
H. olivaceoalbus sensu Hesler and Smith is widely distributed in northern and western North America as well as France and the former U.S.S.R. with Picea (Hesler and Smith 1963).
Distinctive features of H. korhonenii include a gelatinous outer veil covering a dark, fibrillose, inner veil, dark fibrillose veil remnants on the stipe, spores measuring 10-14 × 5.2-7.5 microns and a northern distribution. Not previously reported from western Canada, but has probably been collected and referred to as H. olivaceoalbus sensu Hesler and Smith.”
